No compromise, high-performance noise-isolating earphones that deliver best-in-class benefits and superior value, perfectly matched to the latest product innovations from most music players that support a 3.5 mm stereo phone plug.

Etymotic invented noise-isolating, in-ear earphones. Etymotic's original insert earphone design, developed for auditory research and medical diagnostics, used balanced armature receivers and established these speakers as the gold standard for high-definition, in-ear earphones.

Etymotic makes the world's most accurate noise-isolating headsets and earphones in all price categories. All low-cost earphones are made with dynamic (moving coil) drivers that have undesirable frequency response peaks and weak highs. Etymotic created a design that makes dynamic drivers sound like high-end drivers by inserting a proprietary acoustic side-branch to redistribute energy, smooth the peaks and compensate for weak highs. The result is the mc-series with best-in-class performance under $100.
